Attention: TDR Forum Junkies i can see dumping oil into the fuel if it was going to make a significant difference and was recommended by cummins. BUT, your engine (i dare to say truck) is good for 800-1,000,000 miles with regular maintenance. if the oil took it from 800,000 to say 1. 5M then i would do it. otherwise i will stick with the cummins way.
